2010 Yukon XL Climate control not working

[Chilidawg]

My climate control is stuck in full heat defrost mode. I can push the buttons for different vents and AC and it shows those modes on the screen but nothing happens. Is there a way to reset the climate control or do I need to replace the unit?

A new unit would have to be programmed to the vehicle. A used one with the same options as yours "might" be plug and play. Before doing that, make sure it's not your actuators, get the BCM codes. Then you'll know what's wrong and won't have to throw parts at it guessing.
